I do not believe that that is the problem, in my case it clearly
seems to be a pitch / swizzle problem rather then a synchronizarion
problem, here is what my desktop with gnome shell looks like when
using DRI2:

The DRI2 screenshot is made with Mario's 2 patches on top of

http://lists.freedesktop.org/archives/nouveau/2015-July/021741.html

And then adding Option "DRI" "2" to xorg.conf.

I've also tried disabling EXA using Option "AccelMethod" "none",
but that seems to also automatically disable all DRI, leading to
software rendering.

I discussed this with Ben this morning and he suggested that this
is likely a Mesa issue since with DRI3 mesa rather then the ddx
allocs the surfaces. I've tried disabling swizzling in the
mesa code by forcing nv30_miptree_create() to always take
the code path for linear textures, but that leads to the exact
same result as before that change.

You can tell, just by looking at garbled pattern, what is the actually problem!?

His patches should have defaulted it to DRI 2 I think, so this is
unnecessary. In fact you should have had to say "DRI" "3" to get DRI3
with his patches.

Ah yes. Very different problem indeed. I actually suspect it has to do
with swizzling. Look at the white pattern of the moon -- it's all in a
line. That means that it expected some locality and instead it got
drawn all on a line. If it were merely a stride problem, I'd expect to
see strips of the moon below and offset from one another.

So... take a look at nv30_miptree_from_handle -- I wonder if it can
now receive swizzled textures where it couldn't before.

Unfortunately this is playing near (or past) the limits of my
knowledge as well. My understanding is that DRI3 passes pixmaps around
with dma-buf, aka "bo_from_handle". DRI2 uses some other mechanism
which is not that (I think it just copies stuff around).

Now on nv50+, bo's have "tile flags" (and memtype and probably other
annoyances). The tile flags indicate the specific tiling mechanism
used on that bo (i.e. do you do 32x32 tiles? 32x64? etc). Take a look
at the nouveau_bo_new() call in nv50_miptree.c -- note how it takes a
"bo config" argument. This bo config can then later be retrieved using
some other syscall.

However on nv30 there appears to not be any such thing. The
nouveau_bo_new call just passes in NULL for creating the bo, which
means that there's no way to recover the "are you swizzled"
information after-the-fact.

Presumably you should create a "nv04" bo config section in the union,
and just pass the single "swizzled" bit through. I'm not sure what, if
anything, is required on the kernel side for that. I don't think
there's any optionality in how the swizzling is done for pre-nv50.

Note that in the nv30_miptree logic, mt->swizzled implies that
mt->uniform_pitch = 0, but the level pitch is set "properly" (again,
see nv30_miptree_create).

Hope this sheds some light and doesn't cause you to go in the wrong
direction -- please take everything I say with a grain of salt -- I'm
often a bit off on some of the details.

Cheers,

--- Comment #19 from Ilia Mirkin  ---
Harder to tell, but I think one of two things is happening:

(a) You have the inverse problem. You're getting a linear texture that's being
interpreted as if it were swizzled.
(b) Uninitialized video ram which happened to be some (set of) textures in a
former life.

I'm tending a bit more towards (b) but not 100% sure. I don't know how you
could end up with linear texture data but think it's swizzled, but I'm also not
extremely well-versed in nv30 driver specifics.

The increasing CPU usage is still an issue. Apparently I am the only person to
have this problem. :-(

I have been using Xfce; I switched back to Gnome for a while because I prefer
it. It was disappointing that this has not been resolved.

It seems to be a nvidia-related (or nouveau?) problem. None of the other linux
systems exhibit the CPU usage; the other computers have ATI (built-in or addon)
video controllers.
